Schneider Electric 7- Engineering Services – January 2009
New NFPA 70E-2009 Released
●NFPA Standards Council issued 70E-2009 in July 2008, not widely available until late 2008
●Maintains ‘mandatory’ language of a consensus standard●Represents results of over 500 proposals, 800 comments on previous
70E-2004 version●Many wording changes throughout document; described as ‘same
intent’, but changed for clarity
●PSE processes, methodologies, reports, labels, fully compliant with new version
2009 – Now’s the Time!
Schneider Electric 8- Engineering Services – January 2009
Key Changes to NFPA 70E-2009
● Category 0/1 threshold– now 1.2 cal/cm2 vs former 2.0 cal/cm2
●Ear plugs at all categories, not just >Category 2
● Analysis cut-off point changed - was <240V and <10kA; now 240V or less served by single transformer <125 kVA
● Labeling now requires PPE category or incident energy level
●Analysis to be updated at time of renovation and reviewed periodically not to exceed every 5 years
● Emphasis on maintenance and testing● Emphasis on equipment integrity – ‘exposure
to electrical hazard’ vs ‘working on or near exposed parts’
Schneider Electric 9- Engineering Services – January 2009
Construction Studies – Value!
●Verify equipment ratings● Short-circuit analysis results
●Value engineer project● Head off project problems due to unusual or less optimal designs
●Identify protective coordination issues● Ensure selectivity
●NEC Article 700/701 support (e.g. – Healthcare Projects)● Get the right BOM to satisfy special coordination requirements
●Arc flash analysis● Calculate exposure levels, identify arc flash mitigation opportunities
